Another board that showed up around in a good price is S-type 126.
What do you think about it?
I'm slightly concerned about it's sail top-end - 8.0 - how big you can really get rigged on this board, 7.5?

I find that on our local spot 7.5 conditions are (for me, being 85kg) around good 3B or better, 4B winds.
I think with his weight 8.5 would be a great sail (10.0 for me works well pretty often).
